Description
【Technical field】
The utility model belongs to preform production technical field, more particularly to a kind of three-dimensional acid of preform
Cleaning device.
【Background technology】
One conventional process of existing fiber prefabricated rods is first to make optical fiber prefabricated rod mandrel, then by plug and light
Fine prefabricated rods sleeve column fuses together, and is processed into preform, or carry out OVD synthesis using plug.Prefabricated rods sleeve column one
As from the high-purity synthetic quartz pipe of external import, to reduce cost, and determine the mandrel segment of prefabricated rods key performance then by each
Company oneself produces.The low loss characteristic of optical fiber requires that the purity of prefabricated rods is very high, the requirement particularly to plug, whole
In the production process of prefabricated rod mandrel, the requirement to environment is very high.In plug as qualified products before use, having together very
Crucial process is pickling, and main function is that mandrel surface is handled, by the foreign matter on surface, the metal ion that may be mixed with
It is removed Deng by corrosion, and then when merging with sleeve pipe or being synthesized with OVD, avoids causing because the surface of plug is bad whole
Individual prefabricated rod product it is bad.In pickling generally we use have vertical and horizontal two kinds of pickling machines, each have their own advantage.
The quantity that briefly horizontal pickling function is washed is more, but either has pickling blind spot or can leave roller in mandrel surface
Impression, and this to be us do not wanted to see that, while horizontal pickling machine is especially big to the demand of pure water and acid.Vertical pickling machine
Due to plug is strapped in one by one in tube seat, single or more plug is placed in every tube seat, to the use demand of acid and water
Too big, it is important that but mandrel surface can not contact plastics tube seat when being exactly pickling, otherwise will cause pickling not
Uniformly, mandrel surface weight is had a strong impact on, and then influences the performance of final products, this certainly will require that plastics tube seat is integrally enough
It is straight.And in current vertical pickling machine, only have one, the top strong point to tube seat, the bending to the centre of tube seat is not any
Processing (plastics tube seat in process how many all some cambers, with the increase of usage time, camber can also change).With
Market competition, plug the more does the more long, and surface caused by original design is bad to be on the rise, therefore, to how in vertical pickling
Ensure the overall perpendicularity of PP tube seats in machine, avoid plug from being contacted with tube seat, be very important to improving mandrel surface quality.
In actual production process, when carrying out pickling using vertical pickling machine, plug is placed in what is grown one by one
In plastics tube seat, more plugs are isolated in tube seat using plastic barrier block, and the tube seat for placing plug is placed on acid
On the spray acid mouth of washing machine cavity bottom, top is clamped using a pair of claws.During actual use, due to the length of tube seat
Longer, there is bending centre unavoidably, is easy to touch tube seat inner surface positioned at the plug of the bending section, and then causes to be somebody's turn to do during pickling
There is difference in contact point etching extent, causes pickling quality to reduce.Particularly when tube seat inwall because wear tables occurs in long-term use
Face usually, can more not cause mandrel surface serious out-of-flatness occur, have a strong impact on mandrel surface quality, and then influence final production
The performance of product.Therefore correcting tube seat bending makes it overall vertical enough, is the problem of one currently faced is more serious.
Therefore, it is necessary to a kind of three-dimensional acid dip pickle of preform is provided to solve the above problems.
【Utility model content】
Main purpose of the present utility model is to provide a kind of preform three-dimensional acid dip pickle, corrects and improve
Because of the adverse effect that tube seat curved bel itself comes, the surface quality of prefabricated rod mandrel after pickling is improved, and then improves product quality.
The utility model is achieved through the following technical solutions above-mentioned purpose：A kind of three-dimensional acid dip pickle of preform,
It includes pickling cavity, the tube seat for some tubular structures being erected in the pickling cavity, vertically sets and press from both sides
Hold some clamping devices of the tube seat and the nozzle positioned at the tube seat bottom center.
Further, support is fixedly installed on the pickling cavity both sides inwall, the support is sealing cabin structure.
Further, the tube seat bottom is provided with preform locating groove.
Further, the clamping device include being fixed on cylinder described in both sides in support, by the cylinder drive into
The clamping jaw support of row stretching motion and the clamping jaw being fixed on the clamping jaw support.
Further, the cylinder movable end is fixedly connected with guide cylinder, and the clamping jaw support includes stretching into the guiding
Cylinder in expansion link, by the securing lock nut of the expansion link, the stand frame being fixedly connected with the expansion link and consolidate
The rotating shaft being scheduled on the stand frame.
Further, described clamping jaw one end is set in the rotating shaft and the other end is arranged to and the tube seat surface scan
Arcuate structure.
Further, all clamping jaws on same horizontal line face by a connecting rod connect into one it is whole
Body.
Further, the clamping jaw is located at the both sides of the tube seat and carries out holding action to it.
Compared with prior art, a kind of beneficial effect of the three-dimensional acid dip pickle of preform of the utility model is：
By increasing the clamping device of tube seat, multipoint clamping is taken, and increases clamping dynamics, is easily bent particular for tube seat is answered
Position carry out mechanical hard clamping, the bending to tube seat has carried out good correction, and then ensures that plug is in tube seat
Independent center, avoid contacted with tube seat inwall well, significantly reduce pickling defect, improve pickling process can
By property, and then Improving The Quality of Products and qualification rate.
